Media Player not working after server update

[ThomasPGH]

You don't need to uninstall JMP. On Windows, just exit the application, go to C:\Users\<yourusername>\AppData\Local and delete the two folders "Jellyfin Media Player" and "JellyfinMediaPlayer".

From https://github.com/jellyfin/jellyfin-med.../README.md:

Config File Location

The main configuration file is called jellyfinmediaplayer.conf. You can also add a mpv.conf to configure MPV directly.

Windows: %LOCALAPPDATA%\JellyfinMediaPlayer\
Linux: ~/.local/share/jellyfinmediaplayer/
Linux (Flatpak): ~/.var/app/com.github.iwalton3.jellyfin-media-player/data/jellyfinmediaplayer/
macOS: ~/Library/Application Support/Jellyfin Media Player/
